Simplified gameplay seems to be a massive part of the game, even including an auto-combo system and motionless hyper combos. It's a 6 button game with one button for swapping and a second for infinity stones. Maybe the replacement of a DP spawned from this since the article doesn't mention anything like that or it could just be an omission so who knows?

EDIT: And apparently Roger Jr. has been cut from Tekken 7 because of "animal activists" and the video of a guy punching a kangaroo according to Harada.
